In App Store reviewSee who’s free — and turn that into hanging out. A private, friends-only app.
Group texts are a clumsy way to figure out who's around. Holler is a private, friends-only app for sharing when you're free and turning that into real plans — there's no public feed and no followers, just the people you actually know. Built with React Native and Expo on a Supabase backend, with Postgres row-level security enforcing privacy at the data layer.
Share your availability with only the friends and groups you choose. Nothing is ever public.
Turn “I’m free” into a real hang with invites and in-plan chat that disappears when it ends.
Contacts are matched as salted one-way hashes — your address book is never uploaded in readable form.
Email with verification, Sign in with Apple, or Google — with account deletion built in.
